搞定，结贴，谢谢二位大佬！

C++端：

extern "C" __declspec(dllexport) void __stdcall worldPointToGlobalScreenPoint(int viewNumber, DPoint3d worldPoint, Point2d* globalScreenPoint) {
MSDialogP viewWindow = mdlWindow_viewWindowGet(viewNumber);

DPoint3d viewPoint;
DPoint3d screenPoint;
viewWindow->GetViewport()->ActiveToView(&viewPoint, &worldPoint, 1);
viewWindow->GetViewport()->ViewToScreen(&screenPoint, &viewPoint, 1);
Point2d pointInMdl{ (int)screenPoint.x, (int)screenPoint.y };

if (mdlWindow_isGlobalPointConversionRequired(viewWindow->GetScreenNumber())) {
mdlWindow_globalPointConversionIncrease(globalScreenPoint, viewWindow, &pointInMdl);
}
}

C#端：

[DllImport("MstnLib.dll")]
public static extern void worldPointToGlobalScreenPoint(int viewNumber, Bentley.GeometryNET.DPoint3d worldPoint, ref Bentley.GeometryNET.Point2d globalScreenPoint);

嗯，正在加紧封装中，谢谢！

您需要用C++/CLI封装一下供C#调用，或者通过C#的PInvoke技术（可百度来学习）来调用C++函数。

目前高级的较低层的功能还仅存在于C++中，C#未封装。

C#里面怎么把第二个参数传到mdlWindow_globalPointConversionIncrease中去呢？

这里你最终需要的是globlePoint而不是screenPt2d。我是直接粘过来了另外一个帖子，他想得到screen(monitor) point

// note: you can use the following corrected code piece to get pure windows screen point for the button event.

// both pointInMDLclient and globlePoint are in a window coordinates which is relative to a window rect.

// as you said, Viewport::ViewToScreen don't return screen point in fact.

// please focus on the using of mdlWindow_globalPointConversionIncrease which is the key point here.

// other changes just rename the variable names to make it's meaning more accurate.

// ev.GetViewPoint returns the mouse position of client area of the view window,

// Viewport::ViewToScreen returns the point which is relative to left-up corner of a special client window which

// is the gray area to contain the 8 view windows. The special client window is like the Win32

// MDClient for multi-document program, and we also call it usable area

DPoint3d pointInMDLclient3D = { 0 };

ev.GetViewport ()->ViewToScreen (&pointInMDLclient3D, ev.GetViewPoint (), 1);

Point2d pointInMDLclient = { (int)pointInMDLclient3D.x, (int)pointInMDLclient3D.y };

// in CE, because there is ribbon bar, we must convert the pointInMDLclient to global point which is relative to

// the left-up conner of the main frame window.

Point2d globlePoint = { 0 };

MSDialogP viewWindow = mdlWindow_viewWindowGet (ev.GetViewNum ());

if (mdlWindow_isGlobalPointConversionRequired (viewWindow->GetScreenNumber ()))

mdlWindow_globalPointConversionIncrease (&globlePoint, viewWindow, &pointInMDLclient);

else

globlePoint = pointInMDLclient;

// now use mdlWindow_globalPointToScreen to convert the global point to screen point which is pure windows concept

// but not the Microstation concept, and I don't think there is equivalent C++ method in DgnButtonEvent or other class

Point2d screenPt2d = { 0 };

mdlWindow_globalPointToScreen (&screenPt2d, mdlWindow_viewWindowGet (ev.GetViewNum ()), &globlePoint);

因为ribbon还有minimize状态，所以最好用mdlWindow_globalPointConversionIncrease 进行转换

我看了这个函数的实现，只是在不同窗口之间进行client, screen之间的转换，没有

不知能否直接得那个高度，我再看看。感觉不可以。

dorlig na — Tue, 07 May 2019 03:31:29 GMT

是的。在加上一个判断。

if (mdlWindow_isGlobalPointConversionRequired (viewWindow->GetScreenNumber ()))

mdlWindow_globalPointConversionIncrease (&globlePoint, viewWindow, &pointInMDLclient);

void mdlWindow_globalPointConversionIncrease	(	Point2d *	newGlobalPtP,
		MSWindowP	windowP,
		Point2dCP	oldGlobalPtP
	)

When the Ribbon interface is used, to position popup windows and dynamics correctly, the global point requires a conversion to compensate for the height of the Ribbon.

This function converts the global point by increasing the point by the height of the Ribbon.

这是API文档中的一个函数，我的理解是：因为用了ribbon界面，所以需要对计算的屏幕坐标进行修正。因为调用这个函数比较麻烦，所以我想直接获取那个高度，然后自己计算。

我在DgnPrimitiveTool中用ViewPort的ViewToScreen方法将鼠标点转为屏幕坐标后，发现返回的坐标需要加上这个高度才是正确的显示屏坐标，所以想获取这个高度

请问您想实现什么功能需要获取此高度值？
